THOMAS L. EASLEY, OF IJ-ADDONIA, MISSOURI.

AUTOMATIC GRAIN-WEIGHER.

SPECIFICATION forming part of Letters Patent No. 295,373, dated March 13, 1884.

Application filed September 12, 1883. (Model.) I

To all whom it may concern Be it known that I, T. L. EASLEY, a citizen of the United States of America, residing at Laddonia, in the county of Audrain and State of Missouri, have invented certain newand useful Improvements in Automatic Grain- XVeighers, of which the following is a specification, reference being had therein to the accom panying drawings.

This invention pertains to improvementsin grain-sackers for thrashingmachines, having for its object to effect the sacking of the grain while being thrashed; and it consists of sacksupporting platforms combined with avalved hopper whose valve is adapted to be operated by certain mechanism, and controls the direction of the grain received into the hopper, substantially as hereinafter more fully set forth and claimed.

In the accon'ipanying drawings, Figure 1 is a rear view of my grainsacking apparatus with that side of the inclosing-case removed. Fig. 2 is a vertical section thereof. Fig. 3 is a front view of the same.

In carrying out my invention I employ a casing, A, with an upper closed compartment, A, and two open compartments, A A and which is designed to'be suitably secured to the thrasher at the discharging end of the latter. IVithin the closed eompartment or chamber A is arranged and secured the hopper B, with its mouth preferably secured about flush with the top of the casing A, while its lower end is provided with two broad spouts or tubes,B B,

leading to the lower open compartment, A

and projecting through the bottom of the compartment or chamber A. To the under side of said bottoms are designed to be secured suitable hooks, or other means adapted to support the mouth of the sack intended to receive the grain.

O O are platforms arranged in the open cornpartments, and secured upon side bars, 0 G, which extend into the closed compartment, andhave coiled or other suitable springs, B B, applied thereto, said springs bearing upon crosspins inserted through the upper ends of the side bars and upon the bottom of the closed compartment. Through these side bars, below crossheads or boards 0 arranged upon the said bars, are inserted additional crosspins, (4 a, to hold the springs B B under teninto the slot of the coincident projection or bar b of the platform cross-head, while the free end of the other arm enters a mortised cross bar or rod, E. The cross-rods E are each provided with a spring, 0, preferably arranged so as to encircle the former, its inner or one end bearing against cross-pins d, passed through the rod, while its other end bears against the front inside of the inclosed chamber A, the forward ends of the springrods E bearing in apertures in the same side of the said case.

F is a levercentrally pivoted upon the rear or projecting end of the axis of the valve G of the hopper B, and having weights F sus pended by cords (or rods) f from its ends. Said weights (in lieu of which springs may be used) are notched on their inner sides, near their upper ends, as at f, to receive the pointed rear ends of the spring-rods E.

The operation is as follows: \Vith the valve G of the hopper standing so as to open the entrance or receiving end of one or the other of the tubes or spouts B of the hopper, (only in one of either of these positions it can stand,) the grain received into the hopper will flow through the open tube or spout B and into the sack previously adjusted in position thereunder, as above explained. WVheu the sack has about filled, the platform upon which it rests will descend by reason of the compression of the springs of the side bars of said platform. The platforms (l and (3 are thus caused to descend alternately, each being rigidly secured to two of the vertical side bars, 0. Beam F has projecting through slot 8 in its center the valve-bar F, which forms the only bearingof the beam, and hence the valve Ur is thrown to the right or left by descent of the weights F, and the descending grain is thus directed into the spouts alternately; but

the weight of the grain is not of itself sufficient to cause the outflow of the grain to be cut off instantly, which is the essential element of my invention, as the springs first act and then react under impulse of the descending grain, and prevent the weight of grain being precisely and accurately emptied into thesacks 3 hence simultaneously with the descent of the grain and platform the slotted projection or bar I) of the crosshcad platform side bars acts upon the coincident elbow-lever D, which causes its spring-rod E to retract from the notch of the coincident weight F, and allows this weight to descend upon its platform, thus adding to the weight of the grain its auxiliary weight as a means of instantly and securely closing the valve (I, whereby the grain is measured in just as accurate and precise a manner as obtains ordinarily after the most careful manipulation. The shifting action of the valve will be repeated automatically at the conclusion of each filling operation of the sacks, whereby while one sack is being emptied another is filling.

I-Iaving thus fully described my invention, I claim and desire to secure by Letters Patent 1. In a grain-weigher, the combination of the hopper B, having valve Cr and spouts B, platforms 0, having cross-heads G, springs B and weights F, substantially as shown, and for the purpose described.

2. In a grain-weigl1er, the combination of the platforms 0', notched weights F, secured to lever F, actuating-valve G, elbow-lever D, and spring-rod E, substantially as shown and described.

In testimony whereof I aifix my signature in presence of two witnesses.
